APPARATUS FOR SUPP LYING PASTE TO LABELS.

SPECIFICATION forming part of Letters Patent No. 635,922, dated October 31, 1899.

Application filed April 14, 1899.

. To all whom, it may concern:

Beit known that I, GEORGE DOHERTY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Apparatus for Supplying Paste to Labels, of which the following is a specification.

This is an apparatus particularly intended for supplying paste to labels which are to be adhesively secured to bottles; and the invention consists in the novel construction and arrangement of parts comprised in the said apparatus and fully described below and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my apparatus. Fig. 2 is a central longitudinal vertical section of the same. Fig. 3 is a plan view of the same with the reservoir removed and-a portion of the delivery-tank broken out.

Similar letters of reference indicate corresponding parts.

A represents a delivery receptacle or tank with its sides inclined outward, so that the tank is substantantially frustum shaped. The rear portion of the side wall of this tank is pierced to receive the forward end B of the covered feed-trough 13, whose top B" is provided with a number of holes 0. With the exception of the openings 0 and the entrance into the delivery-tank A this trough is closed on all sides. Mounted on this trough and rigidly secured to the top B thereof around the series of openings 0 is a hollow structure D, open at the upper and lower ends and provided with one or more series of horizontal perforations D.

E represents the top,E the cylindrical sides, and E" the bottom, of the reservoir. The bottom E is provided with a central opening, around which is a downwardly-extending pipe F, open at its lower end. A flange H also extends downward from said bottom E con centrically with the pipe F and between said pipe and the outer edge of the reservoir and is provided with elongated horizontal openings H. This reservoir E is supported securely on the structure D by means of the flange H, which sets closely around said structure. When in the position indicated in the drawings, the elongated openings H inclose and are on a level with the series of perfora- Serial No. 712,966. (No model.)

tions D and the reservoir is connected with and leads into the structure D by means of the pipe F. The interior of the structure is connected with the feed-trough B by means of the openings 0, and the feed-trough leads into the delivery-tank A. A piece of thin, coarse,or perforate cloth,such as cheese-cloth, K is stretched across the horizontal open top or mouth of the tankA and its edges pressed down over the sides of said tank by the ring L. The frustum shape of the tank allows the ring to crowd the cheese-cloth down tightly against the sides and taut over the month.

In practical operation paste is poured into the reservoir through the pipe F by removing and reversing said reservoir, and when the device is first put into use the rest of the apparatus is also filled with paste, so that the entire device is filled, as shown. The operator lays the rear side of the label upon the cheese-cloth K and slightly presses it, with the effect of causing the paste to exude through the cloth upon said under surface of the label, which can then be applied to a bottle. Bya well-known law the paste from the reservoir descends through the intermediate passages into the delivery-tank A and rises to the upper edge thereof, air being supplied through the opening H and holes D,thus keeping close to the under side of the cheese-cloth, so that there is no hollow or concavity on the upper surface of the paste, and the operator can always distribute the paste evenly on the under side of the label, inasmuch as the paste under the cheese-cloth is always perfectly level with the top of the tank. Moreover, it is evident that the operation of applying the paste to the label and the label to the bottle is a cleanly one, inasmuch as no paste leaves the receptacle excepting that which is immediately transferred directly to the label, so that there is no spilling or daubing the paste in the vicinity of the apparatus or on the operator. The entire device is preferably made of sheet-metal.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, isv In an apparatus of the character described, the delivery-receptacle A open at its upper end and adapted to be covered with a perforate fabric K; the binding-ring L the feedtrough B closed at its rear end and opening ing flange H formed With openings IIadapted at its forward endinto the delivery-receptacle to be made coincident with or embrace said 10 and with its top B provided with the openperforations, substantially as described. ilws C; the hollow structure D mounted on V m T 5 th: feed-trough 13 around said openings and GEORGE DOHER L provided with suitable perforations D; and \Vituesses: the reservoir E supported by said structure HENRY XV.
